CASH-REGISTER.

Specification of Letters Patent.

Application filed August 25, 1905. Serial No. 275,701.

To all whom it may concern:

Be it known that I, ADOLPH G. CARLSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Cash-Registers, of which the following is a specification.

This invention relates to improvements in cash registers, and it has for its primary object to provide an improved form of cash register which will be susceptible of being produced on a scale sufli'ciently small to be conveniently carried in the pocket of the user, like a watch.

Other objects of the invention will appear hereinafter from the following descrlp tion.

The invention consists in the features of novelty which will now be described with reference to the accompanying drawings, and more particularly pointed "out in the claims.

In the said drawings, Figure 1 is a face View ofa cash register embodying this invention. Fig. 2 is a back view thereof. Fig. 3 is a face View of one-of the records. Fig. 1 is a transverse section on the line 4:, 4, Fig. 1. Fig. 5 is a section taken on the line 5, 5 Fig. 4. Fig. 6 is a detail section on theline 6, 6, Fig. 5. Fig. 7 is a detail view of a means for holding the hammer-operating pin in position. Fig. 8 is a detail back view of one of the type or printing disks, partially broken away, showing the edge of the Fig. 9 is a face view companion disk also.

Fig. 10 is an enlarged transverse section of the latch and associated parts for securing the record-holding plate in position. Fig 11' is a detail back View of the dog and slide which operates'the spacing wheel. Fig. 12 is an enlarged perspective view of oneof the bin es which support one end of the record-ho ding plate, and Fig. 13 is an enlarged detail section on the line 13, 13, Fig. 11.

1 isa disk, composed of paper or any other suitable material, and preferably of circular form, upon which the record is rinted, and 2 is an operating'knob, wherey a hammer or platen 3 is caused to produce the impression or record upon the disk '1 when the knob 2 is rotated. The knob is provided with a stem or shaft 4:, which carries at its inner end a crank 5, provided wlth a pin or lug 6 adapted to engage one end of the hammer 3 and deflect it or move it in an outward direction against the resistance of a spring 7, to which the hammer is secured, and by which the hammer is supported. The record sheet 1 lies adjacent to the hammer 3 directly under a ratchet wheel 8, which is provided with two spurs 9 and a center pin 10 adapted to enter correspondingly arranged perforations 11, 12, respectively, in the record sheet, thereby causing therecord sheet to remain in place and revolve with the ratchet 8, should the latter be rotated. This rotation of the-ratchet 8 is caused, at the will of the operator, by a dog or pawl 13, which is secured to a slide 14, and held normally withdrawn from the teeth of the ratchet 8 by a spring 15. The spring is provided with a pin or lug 16 (see Fig. 18), which projects through a slot 17 in a plate 18, and engages a ainst the under side of a flange 19 forme on the slide 14; and projecting under the plate 18, as shown in dotted lines in Fig. 2, and in full lines in Figs. 11 and 13, thus pressing the slide 14 to the outer end of its stroke.

The slide 11 is arranged against the side is held against the side of the flange 20 by a screw 22 passing through a slot 23 in the slide 14. One end of the slide 14 is provided with an arm 24, which is arranged in a position accessible to the inner end of a stem 25 capable of being depressed from the exterior, and thereby rotating the ratchet wheel 8' the distance of one tooth, and 'consequently causing the record sheet 1 to make a movement equal to one space, or equal to the distance between the radial lines of printing shown in Fig. 3. The ratchet wheel 8 is centered and held against accidental rotation by a centering dog 26 engaging with the teeth thereof, and secured by a screw 27 to a flange 28 formed on the edge of the plate 18 opposite that carrying the flange 20.- For the sake of uniformity, the dog 26 is formed in one piece with a plate 29, which is capped or flanged over the flange 28, as better shown in Fig. 12, and held in place against flange 28 by a screw 30. The spring 7 is also secured at one end to the face of the plate 18 by means of screws 31, or other suitable agency, and the plate 18 is hinged at one end to a pair of pillars 32. For this purpose, the flanges 28 are continued outwardly toward the rim of the cas1ng 33, and secured to the pillars 32 by pivots 54:, so that the plate 18, together with the ratchet wheel 8 (which is jonrnaled on the inner side of the plate by means of the journal bearing 35) may be turned outwardly on the hinges 3st for the purpose of removing or replacing the record disk 1. I

The end of the plate 18 opposite its hinged end is provided with one or more latches, shown in the form of flat springs 56, secured to plate 18 by the screws 37, which engage with notches in two pillars 38 mounted in a movement-plate 39, or other suitable support, the springs as being provided with thumbpieces at), whereby they may be squeezed together for releasing the springs from the notches of the pillars 38, the plate 18 being held against downward movement on .the pillars 58 by shoulders 4L1, or other means. Against the inner face of the record sheet If, and also penetrated by the spurs 9 and center-pin 10, is a sheet of manifold paper 42, or any other suitable impression produoing medium, and inwardly from this manifold sheet L2that is to say, on the side opposite that on which the record sheet 1S arrangedis located a record-supporting plate 43, provided with an aperture is through which the spurs 9 and center-pin 10 project and move. Une end of this plate l -3 is supported by a pillar l5 situated between the pillars 38, but being shorter than the latter, so as to constitute a support for holding plate against inward movement, while.

outward movement is preventedby the prosimity of the ratchet 8, which 15 of greater diameter than the aperture a l and over-laps plate 4:3. The opposite end of plate ishinged to the pillars by means of arms 46 and the hinge-screws or pivots 34 passing through outwardly-turned lugs 47 on the arms ll (see Fig. l2), both of the plates 18 and 43 being cut away at a position between the arms to to constitute an aperture for the hammer 3 to operate through, as shown in Figs. 2 and 4, whereby the hammer may press the record sheet 1 against the manifold sheet l2, and the manifold sheet, in turn, against the type faces 48, 49, formed on two concentric rings 50, 51, respectively. The inner one of these rings, 51, is formed on or secured to a disk 52, which is attached to a hub 53 ournaled by pin 54 in the movementplate 39, and formed on or secured to this.

hub is a pinion 55, which meshes with a gear 56, secured by ournal 57 to the movement- .plate 1-39 and meshing with a pinion or starwheel 58 on the inner end of a hollow stem 59 surrounding the stoma, and being provided with an operating knob 60 at its outer end, so that when the knob 60 is turned, the hub 53 will be rotated, and a corresponding movement will be imparted to the disk 52 seas-1o The hammer is equipped with a rubber or.

other resilient surface 61 to prevent injury to the type surfaces. This is held in place on the hammer in any suitable way, as, for example, by using a strip of the resilient material passed around the under or inner side of the hammer with its extremities clamped between the outer side of the hammer and the inner side of the spring 7 by means of screws 62, which are screwed into a rib 63 elevated from the back of the hammer into a corresponding opening in the spring 7, whereby the screw-heads 63 which over-lap the edges of said opening may serve to bind the spring and hammer firmly to gether.

. The type ring 50 has its type faces 48 arranged in the same plane as the type faces 49, and the operating face of the hammer 3 is of sufficient length to project across both type rings simultaneously, so as to print from either or both rings, as may be necessary. The type ring 50 is formed on or secured to a disk 64 lying contiguous to the disk 52 and being secured to a gear ring 65, which is journaled on the hub 53 in a posi tion contiguous to the pinion 55 but is free from the hub 53 so that the latter may rotate independently thereof, and meshing with this gear ring 65 is an idler 66 secured to a short shaft 67 in movementplate 39, and to this shaft is also secured a pinion 68 on the outer face of plate 39, and which pinion meshes with a pinion 69 secured to a collar 70 journaled upon a hollow boss 71 formed on the movement-plate 39 around the jour nal 54-, and carrying one of the hands 72,

while the other hand 73 is carried by the journal 54.

Arranged contiguous to the pinion 55 and the gear ring 65 1s a back gear orv idler 74: mounted'upon a slide 75, and adapted, when forced inwardly, to connect the gears 55 and 65 together as one, whereby the rotation of the gear 55 by the knob 60 will also effect the rptation of the gear ring 65 and the consequent rotation of the type ring 50 and the hand 72, which indicates the position of the type ring 50 with respect to thehammcr 3, while the hand 73, which revolves in unison with the type ring 51, indicates the position of the latter, or the type surfaces on the latter, with respect to the hammer 3. The hands 72, 73, revolve at the'lcente'r of a dial which is stationary with relation thereto, and comprises two annular rings 76, 77, bearing characters or matter corresponding to the type surfaces or matter on the type rings 50, 51, and these various items of matter on the dial rings 76, 77, are so spaced and arranged that when the outer hand, which corresponds to the outer type ring 50 points to any item thereon, the corresponding item of the outer type ring 50 will be directly under the hammer 3 in position to be printed from and the same is true with reference to the inner dial ring and matter thereon, that is to say, when the hand 73 points to any one of the numerals or characters thereon, the corresponding numeral or character of the inner type ring 51 will be in position opposite the hammer 3to be printed from. v

The pinion74, is impressed into engagement with the gears 55, 65, for producing simultaneous rotation of the type rings and hands by an exterior knob 78, or push-button, arran ed to act upon the slide 75, which is returne automatically to its outer or disengaged position by a spring 79. There is no especial purpose or reason in rotating the hands 72, 73, and the type'rings simultaneously, but for the sake of simplicity of mechanism, the means which rotate one of these members is utilized by the action of the idler 74 for connecting therotating mechanism of the other member therewith. In

- operation, however, the knob 78 is first depressed and the knob 60 then turned to first set the hand 72 at the first item to be printed.

If it is the date, it is set opposite that point indicated on the dial ring 76, and the date being indicated by the figures in this exemplification of the invention, the inner type ring will be actuated after the hammer 3 has been operated by means of the knob 2 to print the date, as shown on the example of a rec- 0rd in Fig. 3. The word date being printed, the knob 78 is then released, and the knob 60 turned until the small hand 73 points to the first figure of the date, after which the knob 2 is operated for snapping the hammer 3. The knob 60 is then turned again to bring the next figure of the date on the dial ring 77 into position, when the hammer 3 is again snapped by aid of the knob 2. The date being thus produced in a radial line on the record 1, and it being desired to print-an amount and an item below the date,

the spacing knob 25 is then depressed for causing the ratchet ,wheel 8 to rotate the record, as before described with reference to the point of action of the hammer 3. The type rings 50, 51, are then actuated (using the hands 72, 73, as guides) by the knobs 60 and 78, as before described, for setting'the matter in the outer type ring opposite the hammer, which may then be printed from by turning the knob 2 and then setting the numerals 1n theinner type ring, corresponding tothe amount to be printed, successively opposite the hammer, which may be printed from by the successive operation of the knob 2 as such numerals come into position. In order that the hammer 3, which projects across the entire type ring 51, may not print from two of the numerals at one time, such numerals are arranged in tangential lines instead of radial lines, as indicated in Fig. 9, so that it will be impossible to have more than one numeral or character in printing position at one time.

In order that the type rings 50, 51, may be centered or accurately placed by the knob 60, the periphery of the ring 50 is provided with spurs or teeth 80, with which engages a centering dog 81, pivoted to plate 39 and having its end engaging in a notch in the side of the slide 75," whereby the dog 81 may receive the benefit of the spring 79, and secured to the face of disk 64 is a spring 82, which has a dog 83 projecting through an aperture in a disk 64 and engaging with teeth 84 on the periphery of the disk 52, which carries the type rin 51.

When the record-hol ing plate 18 is turned upwardly on its hinge, the end of the hammer 3 is liable to engage with the trippin or lug 6, when in certain positions, and in order that it may be held out of the way of the hammer under this condition, the crank 5 has flattened sides 5 against one of which bears a spring 85 for holding the knob 2 against accidental rotation.
